I've been playing with ax25ipd and have it automatically adding routes
for the callsigns it hears.
If you put 'route ko6ri-4 44.2.1.2' in your ax25ipd.conf file and then
try to connect to ko6ri-4 via your axip interface my station will be
able to answer you because it learned the route from your connect
request. It also adds the route information to the ax25ipd.routes file
so it isn't lost when it's restarted.
If this feature interests you, you can get a copy of ax25ipd at
ftp://bob.midtown.net/ax25ipd/ax25ipd The source is there too as
ax25ipd-42a.tar.gz for the older stuff and ax25ipd-apps-0.0.4tar.gz for
the current stuff. There is a copy I compiled on redhat6 at
ftp://bob.midtown.net/ax25ipd/ax25ipd/ax25ipd-apps-0.0.4/ax25ipd This
copy looks for the ax25ipd.conf file in /usr/local/etc/ax25
